Application filed June 22j, 1925. Serial No. 38,670.

This invention relates to ice shaving or grinding machines adapted foruse by confecioners in making iced confections.

A confection consisting of ground or shaved ice placed in a paper coneand then flavored by saturating the ice with a flavoring syrup has beenfavorably received by the public. Prior to my invention the ground icefor these cones was obtained by scraping a small toothed device over ablock of ice until a suicient quantity of shavings was accumulated tolill a cone. This process necessitating considerable labor and timewasdeemed unsatisfactory. Therefore, it is the principal object of thepresent invention to provide agenerally improved machine capable ofoperation to reduce ice to finely divided particles and to dispense thesame in desired quantities into cones.

In carrying out this object, I provide a feed hopper which is contiguousto a grinding cyllnder wherein blades and a feeding device cooperate toreduce pieces of ice into finely divided particles. These particles aredischarged into a dispenser which is adapted to receive the end of acone. A plunger operates in the dispenser to transfer particles of icefrom the dispenser to the cone.

One form which the invention may assume is exemplified in the followingdescription and illustrated by wayof example in the accompanyingdrawings, in which:

Fig. 1 is a view in central vertical section of a device embodying thepresent forml of the invention.

Fig. 2 is an end elevation of the same.

Fig. 3 is a fragmentary view in plan section taken on line 3-3 of Fig.l.

Referring more particularly to the accompanying drawings, 10 indicates asupporting base which is adapted to be secured to a p counter or thelike for supporting the machine in an operative position Bolted orotherwise secured to the base 10 is the body p portion 11 of themachine.

This body portion 11 includes a hopper 12 which is formed with an openmouth 14 and a concave wall 15 that constitutes both the rear and bottomwall of the hopper. Adjacent the hopper a grinding or shaving chamber 16is formed. This chamber 16 is cylindrical and horizontally disposed in aplane relative to the hopper so that ice fed into the hopper w1ll bedirected by its concave wall 15 into the grinding chamber 16.

As it will be noticed in the drawings the plates 19 are secured to theend of the' cylinder 1.6 and abut against the outer end of the grinding,disk to removably hold it 1n place.

The grinding disk is formed with dia.- metrically opposed radial slots20 which are vertically disposed. Contiguous to one edge 'of each slot,at the outer face of the disk, an oblique surface 21 is formed forrecelvmg cutting or shaving blades 22.` Screws 23 are projected throughslotted openmgs 24 in the bladesand threaded into the disk to secure theblades against the oblique surfaces referred to, with the cutting edgesof the blades projecting inwardly from the inner face of the disk. As`the openings 24 in the blades are slotted, the distance with which theblades project from the inner face of the disk may be adjusted. As thesurfaces upon which the blades `are secured are Oblique and oppositelydisposed, the cutting edges of the blades will be directed at oppositeangles. Therefore when pieces of ice to be ground are force 1n acircular path over the face of the disk, both blades will be effectivein shaving or cutting the ice. The shavings or cuttings will bedire'cted by the obliquely disposed blades through the slots 20 into adisenser 26. Y

the disk and cause it to move in a circular ath thereo'ver, I provide ahelical feeding blade 27 which is disposed concentrically within thechamber 16 and which is of a diameter but slightly less than thischamber. This helical feeding blade 27 is secured on' a shaft 28 whichis horizontally disposed and journalled at its opposite ends in thehopper 12 and in the cutting disk 17. This shaft 28 is collared toprevent it from moving axially.

To revolve the shaft 28 and consequently the feed blade 27, the outerend of the shaft is fitted with a fly wheel 29 having a handle To forcethe ice against the inner face of l a circular path over Ithe cuttingedges of the4 blades. During such movement thecutting e edges of theblades will shave cuttings from the ice and cause them to dischargethrough the slots 20 into the dis enser 26.

The dispenser 26 is cy indrical end vertically disposed and centrallylocated with respect to the vertical axis of the disk 17, and is securedto the outer face thereof by screws. The wall of the dispenser whichabuts against the cuttin disk is formed with a vertical opening w ich isin alignment with the slots 20 formed in the disk so' that the cuttingspassing through the slots 20 will discharge into the dispenser 26. Thelower end of the dispenser 1s open and flared so that a cone may beyieldingly held therein as shown in dotted lines in Fig. 1. The upperend of the dis enser 26 is fitted with a frusto-conical p unger 31having a vertical rod 32 which projects upwardl through and is guidedinto the upper end o the dispenser 26. The outer end of the plunger rod32 is formed with a knob 33 by which the plunger may be actuated. Acompression spring 34 I of ice is broken u is interposed between theunder side of this knob and the upper end of the dispenser 26 andnormally tends to maintain the plunger 31 in its u permost position.

It is o vious that by depressing the plunger 31 through the medium ofthe rod 32 and the knob 33, the plunger will move downwardly in thechamber 25 and discharge an ice cuttings therein through its lower Inactual operation of the device, a block into small pieces which aredeposited in t e hopper 12. A cone is then inserted into the lower endof the dispensing device 26. By revolving the ily wheel 29 by means-ofthe handle 30 the helical feeding blade 27 will be revolved and willfeed the pieces of ice fed into the ho r toward the blades. This willcause t e ltter to shave or grind the ice and to deliver the groundparticles or shavings into the dispenser 26.

When suilicient shavin or ground particles have been accumu ated in thedispenser, the plunger 31 is depressed to force the ground particles orshavings into the cone held at the lower end of the dispenser. As theplunger 31 is frusto-conical the upper end of the ice packed in the conewill be conical and of neat appearance. The cone of the round icetherein may then be removed rom the dispenser and impregnated with aavoring syrup.

It should be stated that a gauge slot 35 is When. it is desired tocleanse the machine,

it is only necessary to remove the small locking plates and remove thedisk 17 and the dispenser 26. All the parts of the machine willttshen beexposed for cleansing or adjustmen From the foregoing it is obvious thata very simple and eicient machine is provided by which ice may berapidly ground to provide so-called snow for ice confections of alldescriptions.

While I haveA shown the preferred form of my invention, it is to beunderstood that various changes in 'its construction may be made bythose skilled in the art without departing from the spirit of theinvention as defined in the appended claims.
